Wanna race like Petacchi?
 
ride the 53x11 at 110 RPM's and produce about 800 watts...

those are some amazing numbers...

figure that's the final stretch, but he's probably turning about 90 RPM's in the 11 for a k or so.

sheesh...

Oops.

I read that as "Pantani"!

I think you meant to say 1800 watts...

AP is definitely on his game

I posted that two times and no one was impressed.

The top track sprinters are scarier, they're hitting 2000 watts...

Devil 05-25-04 01:30 PM

Yeah, but this is after riding 150 - 230 km.

calculate it yourself...

wierd address so hopefully it will work...

a 160 pound rider on a 15 pound bike at 40 mph makes mid 800 watts...without a big wind factor..

same rider at 45 mph is about 1200ish watts...or about 1.7 horsepower.

According to this link, it's about 1112 watts at 40 mph and 1557 at 45 mph.

and that isn't counting the acceleration factor. (uses more watts)

I've tried that 53x11 thing, but it didn't work out too well.

Agreed. To sustain the speed doesn't take nearly what these guys put out ramping it up.

My peak sprinting wattage measured via Powertap is 1300 watts give or take 20 watts (I'm 73Kgs for what it's worth). I can also turn right at 1000 watts for close to 20 seconds. I'm a good sprinter for a Masters 35+ racer and have seen 39-40mph on a number of occasions but I'm no AP... not even close. The only time I even used a 53/11 for a sprint is with a tailwind. AP can probably hold 1400-1500 watts for 15-20 seconds which is unimaginable for us normal guys.

800 watts, I put out 800 watts doing long leadouts tonight on prime laps.

what a stud :rolleyes:

what category did you rise to?

and was this done after 100+ miles of racing, or a roundy round 30 mile crit in a local park?

Brillig 05-26-04 06:58 PM

I do 800 watts when I sneeze.

:)

MacMan 05-26-04 08:02 PM

I might do 800 watts in the car, but that's about it :(

hair07 05-26-04 08:52 PM

watts is for lightbulb's, chumps. i do volts. thousands and thousands of millivolts.
